Hugh Dickins 145e1a71e0 mm: fix the NULL mapping case in __isolate_lru_page() ... George Boole would have noticed a slight error in 4.16 commit 69d763fc6d ("mm: pin address_space before dereferencing it while isolating an LRU page"). Fix it, to match both the comment above it, and the original behaviour. Although anonymous pages are not marked PageDirty at first, we have an old habit of calling SetPageDirty when a page is removed from swap cache: so there's a category of ex-swap pages that are easily migratable, but were inadvertently excluded from compaction's async migration in 4.16.
